Description

This Zelio Logic SR3 compact smart relay / programmable controller uses a supply voltage of 100V-240V alternating current. It has 26 inputs / outputs with screw-clamp terminals. It has compact design, allowing installation on DIN rail. It also offers simple programming, display and diagnosing of malfunctions display and navigation buttons. Its simple ladder programming makes it adapted for non-specialists.

Features

Engineered with a robust high-density configuration, this Zelio Logic smart relay features 26 integrated I/O points, consisting of 16 discrete inputs and 10 normally-open (NO) relay outputs. This comprehensive capacity allows control engineers to consolidate multiple sensors, limit switches, and actuators into a single compact housing, reducing total panel space and eliminating the need for costly external expansion modules.
Operating on a wide rated supply voltage range of 100V to 240V AC (with physical tolerances spanning 85V to 264V at 50/60 Hz), this programmable logic controller runs directly on standard plant power. Industrial electricians can seamlessly wire 100-240V AC discrete inputs without installing extra step-down transformers or external power supplies, significantly minimizing points of failure and accelerating installation time.
Designed with an onboard local LCD display and diagnostic navigation buttons, this unit allows for real-time monitoring of control schemes directly at the machine face. Supporting up to 500 lines of Function Block Diagram (FBD) programming or 240 lines of traditional Ladder Logic, it gives automation technicians the flexibility to troubleshoot processes, force inputs, and adjust variables without dragging a laptop onto the factory floor.
Featuring a compact, low-profile footprint that snaps directly onto a standard 35mm DIN rail or mounts via retractable screw lugs, this controller integrates perfectly into crowded electrical enclosures. To satisfy stringent regulatory audits and corporate safety mandates, the unit carries full UL, CSA, C-Tick, and GL compliance certifications, guaranteeing reliable performance under harsh electromagnetic interference and vibration-heavy processing environments.
